I became a veterinarian because of my love of animals and the challenge of making their lives better. When I was 13 years old, my pet hamster became sick, and my visit to our local veterinarian transformed my life. From that time on, I did everything in my power to become a veterinarian. I went to a high school that had special programs in agriculture and worked on dairy farms during my summer vacations. My college years were marked with intense studying. My hard work paid off as it allowed me to follow a career path that I had long dreamed of.
I earned a Bachelor of Science degree at Cornell University and a Doctor of Veterinary Medicine degree at Cornell in 1979.
I came to Mid Island Animal Hospital in 1981 and became its director in 1983. I have worked throughout the years to expand the services that the hospital provides.
I enjoy all facets of veterinary medicine from internal medicine, surgery and dentistry. In recent years we have added laparoscopic surgery to the services that we offer. I strive to provide the highest quality of medicine for my patients through persistent hard work. Mid Island Animal Hospital has a comprehensive continuing education program that allows its doctors to stay on the cutting edge of veterinary medicine.
My years at Mid Island Animal Hospital have allowed me to grow and serve the community in many ways. In 1993 I engaged in clinical research and helped field test a new drug for Addison’s Disease, and adrenal gland disorder. The results were published in the Journal of the American Veterinary Medical Association and in Current Veterinary Therapy.
In 1998 I became a member of the Long Island Veterinary Medical Association’s Disaster Preparedness Committee. Little did we know that we would be put to the test on September 11, 2001. Suddenly I found myself part of a team responsible for sending veterinarians and assistants to ground zero at the World Trade Center site on a daily basis to care for the search and rescue dogs. We arranged for 24 hour care for the service dogs. This became my “second job” until November 3, 2001. In December 2001 I received the award of Veterinarian of the Year from the Long Island Veterinary Medical Association for my service during this critical period in history.
I have served my alma mater, Cornell University by leading the College of Agriculture and Life Sciences Alumni Association. I was a board member from 2001 and President from 2007 until 2008. I also have represented the College of Veterinary Medicine at several alumni functions. Cornell University has afforded me a lifetime of opportunities and I enjoy helping others attain their goals.
Throughout the years I have invited a variety of community groups to Mid Island Animal Hospital to learn about veterinary medicine and the care of animals. We have opened our doors to nursery school groups, Brownie troops, hearing impaired students, and high school students. We are proud to educate our youth.
At Mid Island Animal Hospital we have a rapidly growing list of students who come to shadow us and were later accepted to the finest veterinary colleges. Several of the students have come back to us to train, and some have even joined our staff. One of my passions is inspiring and mentoring students interested in veterinary medicine. My support of students has been recognized in Veterinary Legacy, a blog written by Dean Emeritus Donald Smith of Cornell University. The blog descibes my path to becoming a veterinarian and my involvement with students (
After practicing over 30 years, I am as excited and enthusiastic about veterinary medicine as ever. In fact, I am never on time for work, I always get there early. It is my privilege to be a veterinarian.

Animals have always been an important part of my life. As a child, I enjoyed the usual assortment of pet turtle, newts, lizard, hamsters, rabbits, and finally cats. I loved zoos, drawing and painting animals and above all, observing wildlife in their natural habitats (whale and dolphin watching, snorkeling in coral reefs, finding marmots and mountain goats in the Western mountains, prairie dogs and coyotes in New Mexico). All kinds of creatures have always fascinated me.
The idea of being a veterinarian, however, did not come to me until halfway through college. I was waffling between anthropology, oceanography, and comparative literature, when I went to stay at my uncle's farm. He and his wife, both doctors, told me if they had to do it over again, they would have been veterinarians. The idea quickly took hold and in no time, I was immersed in pre-vet courses.
I spent the next few years studying extremely hard, working for veterinarians, and volunteering on a dairy farm. My first job was at a practice where Dr. Kornet was an associate veterinarian in Queens. I admired his diagnostic skills and energy and we stayed in touch after that. My hard work paid off. I graduated from Barnard College, Columbia University, summa cum laude and Phi Beta Kappa and was admitted to Cornell Veterinary School.
During vet school, I did externships at the Bronx Zoo and the Oklahoma City Zoo and volunteered at the Avian Clinic treating wild owls and hawks. After graduation from vet school in 1986, I completed a one-year internship at the Animal Medical Center in Manhattan. I rotated through many specialty areas including cardiology, neurology, nephrology, exotic animal medicine, and surgery. It was a year of intense learning and honing of skills through many long days and nights. Being Night Doctor—the sole veterinarian on duty all night for all of Manhattan—as a first year intern, was a trial by fire but taught me many invaluable lessons.
Soon after my internship I got back in touch with Dr. Kornet and was pleased to be able to come to work at Mid Island Animal Hospital in 1987 where I stayed until 1990. I then worked in Westchester until 1996. At that point I was happy to return to Mid Island and have been here ever since.
Mid Island Animal Hospital is a terrific practice because all the veterinarians and staff care deeply about the health and welfare of the patients. The doctors use a team approach, working together on all hospitalized cases and frequently sharing ideas on outpatient cases as well. This constant exchange ensures that many minds tackle any given medical problem and solutions are found even for the toughest cases. In addition, Mid Island is a hospital with state of the art equipment and facilities.
It is a privilege to be able to help this community's pets stay healthy and to strive to overcome illnesses. Few things are as rewarding as seeing a joyful reunion between

They say that the purpose of life is to have a life with purpose. I knew from a very young age that my purpose was to help animals through a career as a veterinarian.

My love of animals prompted me to attend John Bowne High School as an agriculture major. During this time I devoted my summers to working on dairy farms and volunteering at animal hospitals.

I received my Associate Degree in Agriculture at Farmingdale University and a Bachelor of Science Degree at Cornell University. In 1995, I proudly received my Doctorate Degree at the New York State College of Veterinary Medicine, Cornell University.

To further enhance my knowledge and skills as a veterinarian, I also completed a comprehensive one year internship program in small animal medicine and surgery at The Animal Medical Center in New York City. During this time I worked on specialty services including oncology, dentistry, exotics, gastrointestinal and respiratory medicine.

In July of 1996, I started working at Mid Island Animal Hospital and have been here ever since. My attraction to this particular hospital is the wonderful and caring staff, and the common goal of striving to achieve the highest quality of medicine, surgery, and dentistry. We all take pride in our work and it shows through the eyes of the animals we care for.

I have always loved animals, and my heart has always gone out to animals that are sick or injured. While becoming a veterinarian had always been on my mind, my interest in the arts took over at a young age, and my dream of helping animals as a veterinarian was put aside for many years. Later in life, while earning a Bachelor of Science degree at Marymount Manhattan College, I began thinking again about becoming a veterinarian, and hoped that the opportunity had not passed me by. I majored in biology, volunteered at a local animal hospital and at the Prospect Park Zoo, and was accepted into the College of Veterinary Medicine at the Ohio State University in 2004.
Living in the Midwest, I was impressed with the variety of relationships between animals and people. Growing up on Long Island, I only really knew about companion animals. In Ohio, many of our clients were farmers who depended on the health of their animals to survive. Owners of horses, donkeys, llamas and alpacas proved to be people devoted to the health and well being of these animals. My own interests tend toward smaller species. I have a particular love of cats, and am a member of the American Association of Feline Practitioners.
A native of Hicksville, I was glad to return after veterinary school, and felt very fortunate to be offered a position at Mid Island. My family have been clients for 30 years, and Dr. Kornet was an early supporter of my decision to become a veterinarian, offering me a job as an assistant before I started school and during breaks.
Helping animals is a rewarding and challenging job –our patients stretch my knowledge and teach me new things each day. I feel privileged to be working with such a great group of doctors and the wonderful support staff at Mid Island and to be part of the lives of our clients and patients.

I have known since a very early age that I wanted to be a veterinarian. I have always had a love of animals and have had dogs and hamsters throughout my childhood. As a native of Hicksville, my family brought my childhood pets to Mid Island Animal Hospital and I fondly remember those early experiences. I never forgot the compassion with which we were treated here, especially with my dog Lucky, and always intended to come back as a veterinarian after finishing my schooling. I still wear Lucky�s dog tags on my stethoscope as a daily reminder as to why I am here, working to help animals that are as important to their owners as Lucky was to me.
After graduating from Hicksville High School, I majored in biochemistry at SUNY Geneseo in western New York. After a brief foray into biomedical research, I decided to fulfill the prerequisite courses necessary for veterinary school. I realized that there was nothing else I could ever imagine doing with my life and the further schooling was well worth the reward of knowing that I am doing exactly what I always felt I was meant to do. I graduated from Tufts University School of Veterinary Medicine in 2006 and returned to Long Island to practice. I truly enjoy the puzzles of medicine and often bring my work home with me, going over cases in my mind and sometimes out loud with my husband, sister, and father, all of whom are in the medical profession. My professional interests include internal medicine, surgery, and dentistry. I also have a soft spot for beagles and have owned a few over the years. I am blessed to say that I truly love my career and strive every day to learn as much as possible and be the best doctor I can be.
In my free time, I enjoy skiing, traveling, cooking, and reading. My husband and I are new homeowners as well and so we spend a lot of our free time working on and around our new house! I also enjoy spending time with my family: my husband, Trevor, our dogs Skippy and Miles, and our cat Cinder.
